If the Light is Flashing
The following may prevent more serious damage
to your vehicle:
Reducing vehicle speed
Avoiding hard accelerations
Avoiding steep uphill grades
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible
If the light stops ashing and remains on steady,
see “If the Light Is On Steady” following.
If the light continues to ash, when it is safe to do
so, stop the vehicle. Find a safe place to park
your vehicle. Turn the key off, wait at least
10 seconds and restart the engine. If the light
remains on steady, see “If the Light Is On Steady”
following. If the light is still ashing, follow the
previous steps, and see your dealer for service as
soon as possible.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully
install the cap. SeeFilling the Tank on page 346.
The diagnostic system can determine if the fuel cap
has been left off or improperly installed. A loose or
missing fuel cap will allow fuel to evaporate into the
atmosphere. A few driving trips with the cap
properly installed should turn the light off.
Did you just drive through a deep puddle
of water?
If so, your electrical system may be wet. The
condition will usually be corrected when the
electrical system dries out. A few driving trips
should turn the light off.

Steps for Determining Correct Load Limit
1. Locate the statement “The combined
weight of occupants and cargo should never
exceed XXX kg or XXX lbs” on your
vehicle’s placard.
2. Determine the combined weight of the driver
and passengers that will be riding in your
vehicle.
3. Subtract the combined weight of the driver
and passengers from XXX kg or XXX lbs.
4. The resulting gure equals the available
amount of cargo and luggage load capacity.
For example, if the “XXX” amount equals
1400 lbs and there will be ve 150 lb
passengers in your vehicle, the amount of
available cargo and luggage load capacity is
650 lbs (1400−750 (5 x 150) = 650 lbs).5. Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated in
Step 4.
6. If your vehicle will be towing a trailer, the load
from your trailer will be transferred to your
vehicle. Consult this manual to determine how
this reduces the available cargo and luggage
load capacity for your vehicle.
If your vehicle can tow a trailer, seeTowing a
Trailer on page 327for important information
on towing a trailer, towing safety rules, and
trailering tips.

Recreational Vehicle Towing
Recreational vehicle towing means towing your
vehicle behind another vehicle — such as behind
a motorhome. The two most common types of
recreational vehicle towing are known as dinghy
towing, towing your vehicle with all four wheels on
the ground, and dolly towing, towing your vehicle
with two wheels on the ground and two wheels up
on a device known as a dolly.
With the proper preparation and equipment, many
vehicles can be towed in these ways. See
“Dinghy Towing” and “Dolly Towing,” following.
Here are some important things to consider before
you do recreational vehicle towing:
What is the towing capacity of the towing
vehicle? Be sure you read the tow vehicle
manufacturer’s recommendations.
How far will you tow? Some vehicles have
restrictions on how far and how long they
can tow.
Do you have the proper towing equipment?
See your dealer or trailering professional
for additional advice and equipment
recommendations.
Is your vehicle ready to be towed? Just as
you would prepare your vehicle for a long
trip, you will want to make sure your vehicle is
prepared to be towed. SeeBefore Leaving
on a Long Trip on page 310.
Dinghy Towing
Notice:If you tow your vehicle with all
four wheels on the ground, the drivetrain
components could be damaged. The repairs
would not be covered by your warranty. Do not
tow your vehicle with all four wheels on the
ground.
The vehicle was not designed to be towed with all
four wheels on the ground. If your vehicle must
be towed, you should use a dolly. See “Dolly
Towing” that follows for more information.
326

Dolly Towing
Your vehicle can be towed using a dolly. To tow
your vehicle using a dolly, follow these steps:
1. Put the front wheels on a dolly.
2. Put the gear shift lever in PARK (P).
3. Set the parking brake and then remove the
ignition key.
4. Clamp the steering wheel in a straight-ahead
position.
5. Release the parking brake.
Towing a Trailer
{CAUTION:
If you do not use the correct equipment
and drive properly, you can lose control
when you pull a trailer. For example, if the
trailer is too heavy, the brakes may not
work well — or even at all. You and your
passengers could be seriously injured. You
may also damage your vehicle; the
resulting repairs would not be covered by
your warranty. Pull a trailer only if you have
followed all the steps in this section. Ask
your dealer for advice and information
about towing a trailer with your vehicle.
Your vehicle can tow a trailer if it is equipped with
the proper trailer towing equipment. To identify
the trailering capacity of your vehicle, read
the information in “Weight of the Trailer” that
appears later in this section. Trailering is different
than just driving the vehicle by itself.
327

Trailering means changes in handling,
acceleration, braking, durability, and fuel
economy. Successful, safe trailering takes
correct equipment, and it has to be used properly.
That is the reason for this part. In it are many
time-tested, important trailering tips and safety
rules. Many of these are important for your safety
and that of your passengers. So please read
this section carefully before pulling a trailer.
Load-pulling components such as the engine,
transaxle, wheel assembly, and tires are forced to
work harder against the drag of the added
weight. The engine is required to operate at
relatively higher speeds and under greater loads,
generating extra heat. What is more, the trailer
adds considerably to wind resistance, increasing
the pulling requirements.If You Do Decide To Pull A Trailer
Here are some important points:
There are many different laws, including
speed limit restrictions, having to do with
trailering. Make sure your rig will be legal, not
only where you live but also where you will
be driving. A good source for this information
can be state or provincial police.
Consider using a sway control. Ask a hitch
dealer about sway controls.
Do not tow a trailer at all during the rst
1,000 miles (1 600 km) the vehicle is driven.
The engine, axle or other parts could be
damaged.
Then, during the rst 500 miles (800 km) that
the vehicle tows a trailer, do not drive over
50 mph (80 km/h) and do not make starts at full
throttle. This helps the engine and other parts
of the vehicle wear in at the heavier loads.
Obey speed limit restrictions when towing a
trailer. Do not drive faster than the maximum
posted speed for trailers, or no more than
55 mph (90 km/h), to save wear on the
vehicle’s parts.
328

There are three important considerations have to
do with weight:
The weight of the trailer
The weight of the trailer tongue
The total weight on the vehicle’s tires
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than 1,000 lbs
(450 kg). But even that can be too heavy.
It depends on how you plan to use your rig. For
example, speed, altitude, road grades, outside
temperature and how much the vehicle is used to
pull a trailer are all important. It can also depend
on any special equipment that is on the vehicle,
and the amount of tongue weight the vehicle can
carry. See “Weight of the Trailer Tongue” later
in this section for more information.Maximum trailer weight is calculated assuming
only the driver is in the tow vehicle and it has all
the required trailering equipment. The weight
of additional optional equipment, passengers and
cargo must be subtracted from the maximum
trailer weight.

Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important
weight to measure because it affects the total
or gross weight of the vehicle. The Gross Vehicle
Weight (GVW) includes the curb weight of the
vehicle, any cargo in it, and the people who will be
riding in the vehicle. If there are a lot of options,
equipment, passengers or cargo in the vehicle,
it will reduce the tongue weight the vehicle
can carry, which will also reduce the trailer weight
the vehicle can tow. And if you tow a trailer,
you must add the tongue load to the GVW
because the vehicle will be carrying that weight,
too. SeeLoading Your Vehicle on page 319
for more information about the vehicle’s maximum
load capacity.When using a weight-carrying hitch, the trailer
tongue (A) should weigh 10 percent to 15 percent
of the total loaded trailer weight (B).
After the trailer is loaded, weigh the trailer and the
tongue, separately, to see if the weights are
proper. The correct weight could be achieved
simply by moving some items around in the trailer.
